5593efec01 Fix stereoscopy drawing for camera background
Part of the fix was to get gputexture to use an array to accomodate each
eye. This takes care of viewports showing individual Left or Right
views.

For the combined view the fix was in overlay_image.c:camera_background_images_stereo_setup.

Note 1: Referece images are still not supporting stereo.

Note 2: For painting, and getting image bindcode I'm hardcording a
single-view experience.

Note 3: Without D6922 stereo is too broken to even test this patch.
With D6922 + this patch the fullscreen modes work (anaglyph/interlace
not yet).

b9f6d033be Eevee: internal support for arbitrary number of volume grids
This has no user visible impact yet since smoke volumes only support a fixed
set of attributes, but will become important with the new volume object.

For GPU shader compilation, volume grids are now handled separately from
image textures. They are somewhere between a vertex attribute and an image
texture, basically an attribute that is stored as a texture.

c8acb6dd6c Smoke: put density/color in separate textures, fixes for workbench shader
This is more in line with standard grids and means we don't have to make
many special exceptions in the upcoming change for arbitrary number of volume
grids support in Eevee.

The workbench shader was also changed to fix bugs where squared density was
used, and the smoke color would affect the density so that black smoke would
be invisible. This can change the look of smoke in workbench significantly.

When using the color grid when smoke has a constant color, the color grid
will no longer be premultiplied by the density. If the color is constant
we want to be able not to store a grid at all. This breaks one test for
Cycles and Eevee, but the setup in that test using a color without density
does not make sense. It suffers from artifacts since the unpremultiplied
color grid by itself will not have smooth boundaries.

18e3615a68 Face Sets: Use white color for a default Face Set to enable the overlay
This introduces a variable to store a face set ID which is going to be
rendered white. When initializing a mesh or randomizing the colors, this
variable gets updated to always render a white face set. This way the
face set overlay can be enabled without adding colors to the mesh if
face sets are not in use. After creating the first face set, new colors
are generated randomly like usual.

The face set stored as default does not have any special meaning for
tools or brushes, it just affects the rendering color.

598ab525da Cleanup: Replace ABS/SQUARE/CUBE with function calls
While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.

There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).

For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

38d6533f21 Sculpt Face Sets
Face Sets are the new system to control the visibility state of the mesh in sculpt and paint modes. They are designed to work in modes where brushes are the primary way of interaction and they provide much more control when working with meshes with complex shapes and overlapping surfaces.

This initial commit includes:
- Sculpt Face Sets data structures and PBVH rendering.
- Face Set overlay and opacity controls.
- Sculpt Undo support.
- Remesher reprojection support. The visibility state of the mesh is also preserved when remeshing.
- Automasking and Mesh filter support.
- Mask expand operator mode to expand Face Sets (Shift + W) and flood fill areas by connectivity (press Ctrl while expanding).
- Sculpt Mode Face Sets and Visibility API.
- Sculpt Face Sets creation and visibility management operators.
- Operator to randomize the Face Sets colors.
- Draw Face Sets brush tool to create and edit the Face Sets. Drawing on the mesh creates a new Face Set. Pressing Ctrl before drawing modifies the Face Set under the brush at the beginning of the stroke.
- Updated keymap and menu to work with Face Sets from Sculpt Mode (H to toggle visibility, Alt + H to show all, Shit + H to hide).
- Pie menu on the W key with Face common Sets operations.

Know limitations:
- Multires support. The Face Sets and Visibility API needs to be implemented for Multires.

4a373afa5f Sculpt: Cloth brush
This brush has a simple physics solver that helps when sculpting cloth.

- The mass and the damping properties of the simulation are properties of the brush.
- It has two additional radius control to limit the influence and falloff of the simulation.
- Masked vertices are pinned in the simulation, and it applies the sculpt gravity directly in the solver.
- The Cloth Brush has 7 deformation modes with 2 falloff types (radial and plane).

The brush can create the constraints only on the required PBVH nodes, so the simulation is isolated on high poly meshes. As long
as the brush size is not too big it should be possible to keep it real time.

Known issues:
- The way constraints are created is extremely basic and it creates repeated constraints. Maybe there is another way to create fewer constraints while keeping the simulation quality decent. This part can also be multithreaded. (As it is it works ok, but it could be better)

In blender 2.79 you could use a render result as a camera background
image. This is useful during layout/compositing. During Blender 2.80
development there were 2 issues introduced that removed this feature.

* to receive a render result the image required a lock. This lock wasn't passed and therefore no image was read from the result. Generating an GPUTexture from an Blender image also didn't do the locking.
* the iuser->scene field wasn't set what is required for render results.

This change adds an optional `ibuf` parameter to `GPU_texture_from_blender` that can be passed when available.

7d8a186335 Fix T73133: UDIM texture count in Eevee is limited by OpenGL
Based on @fclem's suggestion in D6421, this commit implements support for
storing all tiles of a UDIM texture in a single 2D array texture on the GPU.

Previously, Eevee was binding one OpenGL texture per tile, quickly running
into hardware limits with nontrivial UDIM texture sets.
Workbench meanwhile had no UDIM support at all, as reusing the per-tile
approach would require splitting the mesh by tile as well as texture.

With this commit, both Workbench as well as Eevee now support huge numbers
of tiles, with the eventual limits being GPU memory and ultimately
GL_MAX_ARRAY_TEXTURE_LAYERS, which tends to be in the 1000s on modern GPUs.

Initially my plan was to have one array texture per unique size, but managing
the different textures and keeping everything consistent ended up being way
too complex.

Therefore, we now use a simpler version that allocates a texture that
is large enough to fit the largest tile and then packs all tiles into as many
layers as necessary.

As a result, each UDIM texture only binds two textures (one for the actual
images, one for metadata) regardless of how many tiles are used.

Note that this rolls back per-tile GPUTextures, meaning that we again have
per-Image GPUTextures like we did before the original UDIM commit,
but now with four instead of two types.
